Technical Developments Fundamental Concepts of the Digital Differential Analyzer Method of Computation Introduction.—Two fundamentally different approaches have been developed in using machines as aids to calculating. These have come to be known as analog and digital approaches. There have been many definitions given for the two systems but the most common ones differentiate between the use of physical quantities and numbers to perform the required automatic calculations. In solving problems where addition, subtraction, division and multipli- cation are clearly indicated by the numerical nature of the problem and the data, a digital machine for computation is appropriate.

  • Pat Hume Was Canada's Pioneer of Computer Programming
    OBITUARY Pat Hume was Canada’s pioneer of computer programming MICHAEL LENNICK (includes correction) Published Tuesday, Jul. 30 2013, 10:22 PM EDT Last updated Thursday, Aug. 01 2013, 4:48 PM EDT Pat Hume has been called a pioneer of Canadian computing – an oft-repeated description dating back to his 1952 work developing software for Canada’s first electronic computer, FERUT. Renowned as one of Canada’s innovators of computer science, he wrote his earliest programs out by hand on paper tape, which then had to be fed into the university’s massive vacuum tube computer for numerical processing. The former master of the University of Toronto’s Massey College, and writer and performer on some of the earliest episodes of the CBC show The Nature of Things, Prof. Hume was one of the university’s first faculty members to work with FERUT. In those days computers were vastly expensive, gymnasium-sized, vacuum-tube-laden monsters, designed and hand-built to order for the few universities and military organizations that could afford them. Having evolved from Second World War-era mechanical number-crunchers used to calculate gun trajectories, the first electronic computers, including ENIAC and MANIAC, were initially put to work processing subatomic reactions for the American hydrogen bomb project. Prof. Hume’s pioneering efforts were far more docile, directed toward the invention of programming and operating systems that would make the computer more of a universal tool. His research led directly to the development of some of the world’s earliest software, including TRANSCODE, a predecessor to modern computer programming.

Introduction There has been a considerable effort in many countries to set up cultural and research institutions to preserve for posterity computer artifacts that document the cultural history of the information age. The mission of these institutions is to showcase the outstanding contributions of these nations to the development of computer and information technologies. The list of such institutions is long and includes: the Charles Babbage Institute (USA), the Computer History Museum (USA), the Heinz Nixdorf MuseumsForum (Germany), German Museum of Tech- nology (Germany), Computer Museum, Achen (Germany), The National Museum of Computing (UK), The Centre for Computer History (UK), the Computer Museum at Bletchley Park (UK), ACONIT computer museum (France), Computer Museum and Archive, Paris (France), Computer Mu- seum of the University of Amsterdam (The Netherlands), the Finish Data Processing Museum Association (Finland), the Computer Museum of the Japanese Information Processing Society, Monash Museum of Computing (Australia), the Canada Science and Technology Museum (Canada), York University Computer Museum (Canada). 1 Fig. 1.

  • Trixie Moorsley, the First Woman, and Person, To
    Trixie Worsley It's interesting how Trixie Worsley, who is believed to have earned the very first doctorate in computer science, supervised by Douglas Hartree and Alan Turing at Cambridge, is often identified as "the first woman in the world to earn a doctorate in computer science" as if the idea that she was the first person to do this had not even occurred writers. She was a woman, so she must be the "first woman," and an imaginary innovative prior man is implied. Amongst the first computer scientists in Canada, she was certainly the first woman in the field here. She focused on writing software, development of computer libraries, scientific computation and was co-author of the first compiler Transcode (vital to physicists) as well as teaching in the new field of computer science. Her work provides insight into the history of the nascent field of computer science. She published her computational insights and solutions for problems in physics, biology and computer science. Beatrice Helen Worsley (1921-1972), a quiet and accommodating girl known as Trixie, was born in Queretaro, Mexico, to English parents who had moved to Mexico so her father could work in her mother's family's textile mill. This mill had been destroyed by rebels in 1917, and Trixie's future parents had had to move again so her father could instead work for Rio Grande group’s CIMSA mills. Trixie's mother home-schooled her and her older brother, and the family remained cut off from the local community for safety during this turbulent time in Mexico's history.

Introduction By the 1930s, mechanical and electromechanical calculators from Burroughs, Felt & Tarrant, Marchant, Monroe, Remington, Victor, and other manufac- turers had penetrated all aspects of a modern office operations. It seemed that the mathematical tables could handle the rest in science and engineering. However, certain branches of science and engineering reached a calculat- ing barrier that prevented further progress unless an automated method of dealing with complex operations, such as solving linear equalities, differential equations, etc. could be found. What was needed was a new type of a calculating machine that could per- form large-scale error-free calculations by following, in a mechanical way, a predefined sequence of operations, that is, by following a program. The 1930s was a crucial period in the development of computing. Not only the first designs of computers started to appear in Europe and the US but also a groundbreaking theoretical research on computing was initiated. In this lecture we shall take a look at the pioneering work on digital com- puters. We shall discuss the origins of the first computers and their intended use. We shall talk about people and events leading to the first designs and their impact on society and on the development of future computer industry.
